Plugs into which you insert a USB charging cord usually offer 1A. Specialised USB charging modules can offer anything from 1–5A. The cable that you use to charge a device can also affect speed. Thinner cables reduce amperage, leading to longer charging times.
What is the highest amp USB charger?
In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A); with USB 3.0, it moves up to 900mA (0.9A). The charging downstream and dedicated charging ports provide up to 1,500mA (1.5A).
How many amps does A charger take?
A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery.

Will A 3 amp charger hurt my phone?
Nothing, because nothing is there to ask for the amperage needed to produce that kind of power. It goes to a step down converter usually to 5 volts at 2 amps. Fast charging is 9 volts at about 1.7 amps. I would not recommend plugging your phone into a standard home 110 outlet.
Is 2.4 amps fast charging?
The same mobile phone with a 2.4A charger will take 1.25 hours to charge. All this assuming a 100% efficiency, which is not real: usually efficiency is around 80% or 70%, so the times will be slightly higher. In other words, the 2.4A charger is 58% faster than the 1A charger, a remarkable difference.
Is it better to charge a battery at 2 amps or 10 amps?
It is best to slow charge the battery. Slow charging rates vary depending on the battery’s type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
